ERVN LEVI BATES, OF OAKDALE, NEBRASKA.

GATE-GPENER.

Application led April 14, 1917.

To all whom t may concern.'

i Be it known that I, Ervin LEVI Barns, a citizen of the United States,residing at Oakdale, in the county of Antelope, State of Nebraska, haveinvented a new and useful Gate-Opener; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The present invention relates to a gate opening mechanism, and has forits object character which embodies novel features of constructionwhereby a gate can be opened by the occupant of an approaching vehicleand subsequently closed after passing through the gate opening withoutthe necessity of dismounting from the vehicle.

Further objects of the invention are to provide a gate opening mechanismwhich is comparatively simple and inexpensive in its construction, whichcan be easily manipulated, and which is dependable in its action and notliable to get out oferepair.

With these and other objects in view, the invention consists in certainnovel combinations and arrangements of the parts as will more fullyappear as the description proceeds, the novel features thereof beingpointed out in the appended claims.

F or a full understanding of the invention, reference is to be had tothe following description and accompanying drawings, in which Figure 1is a side elevation of a gate opening mechanism constructed inaccordance with the invention.

Fig. 2 is a transverse sectional view through the same on the line 2 2of Fig. 1.

Fig. 3 is a detail sectional view of one of the bearing supportingsleeves.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawings, which illustrate a preferred embodiment ofthe invention, the reference numerals 1 designate a pair of spacedstandards which are arranged upon one side of the roadway and have theupper ends thereof bifurcated to provide for the pivotal mounting of theoperating levers 2. rlhe gate itself may be of any suitableconstruction, although in the present instance it is shown as formedwith upright i Speccaton of Letters Patent.

end bars 3 connected attheir middle points by a horizontal rail 4, theextremities of the end bars being connected by horizontal rods 5 anddiagonal braces 6. 1f desired, woven wire netting may be stretched uponthe gate.

The end bar 3 at the pivot end of the gate is rigidly secured to themiddle portion of a horizontal bar 7 which is arranged at right anglesto the plane of the gate and journaled between the two standards 1 so asto turn about a horizontal axis. Inthe present instance the extremitiesof `the. horizontal bar 7 are shown as terminating in trunnions 7 awhich are journaled within suitable bearings S upon sleeves 9 whichare'fitted upon the respective standards 1 and firmly secured thereto atthe proper elevation. These sleeves 9 may be conveniently formed ofsheet metal, and are provided at their lower ends with integrallaterally projecting Vsleeves 10 which receive and position theextremities of a horizontal strut member 11 which is arranged betweenthe standards 1 and below the pivot bar 7. This horizontal strut 11 maybe secured to the positioning sleeves 10 and standards 1, and serves tohold the standards 1 properly spaced from each other. A horizontal tierod 12 is ar ranged under the strut 11 and connects the standards 1,extending through the latter and having the ends thereof threaded toreceive nuts 13 which bear against large washer members 14e. lt willthus be obvious that the. strut 11 and tie rod 12 coperate with eachother to hold the standards 1 at exactly the proper distance apart,since the strut prevents the standards from coming together, while thetie rod prevents the standards from spreading apart.

Horizontally disposed diagonal braces 15 extend between the pivot bar 7and the central rail 4f of the gate in order to hold the gate rigidly inproper position and prevent lateral swinging thereof. ,secured to thishorizontal rail lof the gate at a point suitably spaced from the pivotbar 7 are the laterally projecting arms 16 which terminate in balls 16aupon which socket members 1Gb are loosely fitted. The socket members 1Gbare connected by coil springs 21 to cables 17 which extend downwardlyfrom the inner ends of the operating levers The outer and longer ends ofthe operating levers 2 extend in opposite directions along the side ofthe road and have suitable cables or handles 1S applied thereto. Aperson approaching the gate from either direction will pull downwardlyupon the handle 18 of the cor-V responding operating lever 2 and therebycause the gate to be swung over on the opposite side of the standards 1.The resiliency of the springsQl will adinit of the gate being easilyswung beyond a dead center whenV sides being flared, as indicated at2OEL for the vto swing downwardly into a closed position.

purpose `of directing the gate into the space between the sides when thegate is permitted Having thus described the invention, what I claim asnew and desire to secure by Iletters l'atent, is

1. A device of the character described, in-

Y cluding a pair of spaced standards, sleeves slidably mounted upon therespective standards and provided with corresponding bearings, means forsecuring the sleeves in anadjusted position, a horizontal strutextendingbetween thek standards, positioning sleeves carried by and projectinglaterally Uoples of this patent may be obtained for frein the beforeinentionedsleeves, said positioning sleeves receiving the ends of thehorizontal strut, a horizontal bar extending between the standards andhaving its ends ]ournaled within the bearings of the sleeves,

a gate having one end thereof rigid with the Y horizontal bar andniounted to swing upwardly in a vertical plane with the axis of thehorizontal bar as a center, operating levers pivotally mounted` upon theupper portions of the standards, andl cable connections between theoperating levers and the gate.

2. A device of the character described, iiicluding a pair of spacedstandards, a gate pivotally mounted between the standards to swingupwardly in a vertical plane about a horizontal aXis, operating leverspivotally mounted upon the upper ends of the standards, arms projectinglaterally froni the sides of the gate and terininatingin balls, socketsloosely applied to the balls, and cable connections between the socketsand the opf erating levers.

In testiinony whereof I have signed iny naine to this'specication in thepresence of two subscribing witnesses.
